“…Related to the importance of the density effects is the vertical disaggregation and resolution of flow processes in the modelling system and associated with that whether a 2D-crosssectional representation of processes is better at capturing the saltwater movement than a 2D lateral and distributed representation (Reilly & Goodman, 1985). From Table 1, it appears that the former tends to estimate longer recovery times (6-10 years) (Violette et al, 2009) compared to the latter (2 years) (Sivakumar & Elango, 2010) for the same affected area in southeast India, which suggest that representation of the vertical flow component is important. Supporting such knowledge generation would be to ensure monitoring of deeper groundwater in the affected systems, as so far, only upper groundwater has been monitored.…”

“…The infiltration from the land surface during the inundation is shortlived but covers a large area, whereas the percolation from depressions comprises large localized volumes infiltrated over much longer times (Chidambaram et al, 2010). Prolonged effects of saltwater leaching has been documented from the entrapment of tsunami water in the soil profile during dry periods leading to precipitation of salts that subsequently get washed out in rainy periods (Chidambaram et al, 2010;Sivakumar & Elango, 2010;Violette et al, 2009). If the Tsunami run-up is high enough to overflow a local topographical divide, larger parts of the tsunami water will flow inland and not retract to the sea, with an overall larger impact.…”

“…In the past decades, a great many efforts were undertaken in addressing uncertainties in water quality management through stochastic programming approaches (e.g., dynamical programming, chance-constrained programming, and recourse model) (Anderson et al 2000;Kentel and Aral 2004;Maqsood et al 2005;Qin and Huang 2009;Huang et al 2010;Sivakumar and Elango 2010). For example, Fujiwara et al (1988) proposed a chance-constrained programming method for identifying optimal waste removal strategies that could mitigate the impacts of the waste discharges on the dissolved oxygen (DO) concentration in a water body, where probability of violating the DO deficit standard was investigated.…”

A recourse-based nonlinear programming (RBNP) method is developed for stream water quality management under uncertainty. It can not only reflect uncertainties expressed as interval values and probability distributions but also address nonlinearity in the objective function. A 0-1 piecewise linearization approach and an interactive algorithm are advanced for solving the RBNP model. The RBNP is applied to a case of planning stream water quality management. The RBNP modeling system can provide an effective linkage between environmental regulations and economic implications expressed as penalties or opportunity losses caused by improper policies. The solutions can be used for generating a variety of alternatives under different combinations of pre-regulated targets, which are also associated with different water-quality-violation risk levels and varied potential economic penalty or loss values.

“…Being a coastal region, it is prone to frequent catastrophic cyclones and floods. The region was also severely affected by the 2004 tsunami (Rajamanickam et al 2006;Sivakumar and Elango 2010). It receives high intensity of rainfall during north-east monsoon (OctoberDecember), moderate during south-west monsoon (JulySeptember) and low during transitional period.…”

Assessment of possible sources that control the groundwater quality was carried out in the Cauvery deltaic region, India, since domestic and agricultural water requirements are largely met by groundwater abstraction. Major ion and bromide contents are high in groundwater in the coastal wells. Spatial and vertical distributions of ions reveal that the shallow wells and wells in coastal parts have high chloride, nitrate, ammonium and phosphate. Groundwater quality assessment was carried out using the prescribed limits of World Health Organization and Bureau of Indian Standards which indicates that 55 % of samples are not fit for drinking. Integrated suitability map for drinking was created based on the concept that if the water sample exceeds any one of the standards by World Health Organization or Bureau of Indian Standards, the well is not fit for drinking. Groundwater quality for agricultural activities was assessed using electrical conductivity, sodium adsorption ratio, residual sodium carbonate, United States salinity laboratory diagram and Food and Agricultural Organization methods. According to Food and Agricultural Organization, 84 % of samples are classified as low sodium water and are suitable for all crops and soils. It was found that the water quality in this area is affected by improper disposal of waste, sewage/drainage canals near the wells, irrigation return flow, application of agrochemicals and saline water intrusion in the coastal region. Further, integrated suitability map produced in this study will be useful for future groundwater development and planning in this area. The suitability map needs to be updated periodically for proper management plan to preserve the groundwater resource in this region.
